Yes. You can decline to complete a purchase rather than accept a credit-card surcharge. That does not automatically mean the merchant broke the law, however. Whether the fee may be imposed depends on the transaction’s location, whether you had a workable fee-free payment option, how and when the fee was disclosed, and the applicable card-network rules.
A merchant generally cannot be forced to complete the sale on terms you prefer. Your practical choices are to use an available no-fee payment method, ask the merchant to remove a prohibited or misstated charge, or walk away. The rules below explain how to evaluate the fee before you pay.

“Can I refuse?” and “Can the merchant charge it?” are separate questions
You can stop the transaction at any time before agreeing to pay. You may also choose another payment method if the merchant offers one for the same purchase. That consumer choice is different from a legal right to make the merchant sell the item without a surcharge. The cited federal guidance does not create a general right to compel a sale on different terms.
The merchant’s authority to add a fee is determined separately by state or territorial law, federal consumer-protection requirements, and payment-network rules. A surcharge can therefore be lawful in one location and prohibited in another, or lawful only after specific disclosures.

The Federal Trade Commission (FTC) describes payment-processing fees in its FAQ on the Rule on Unfair or Deceptive Fees. The FTC’s published position is that “Businesses may charge or pass through credit card or other payment processing fees if otherwise permitted by law.” The words “if otherwise permitted by law” matter: the federal rule does not wipe out state surcharge bans.
How the FTC framework treats a credit-card fee
When the merchant requires a credit card
If the business requires a credit card for the offered transaction and does not provide a viable fee-free alternative, the processing charge is treated as mandatory under the FTC rule. A mandatory fee must be included in the total price presented to the consumer, rather than added only after the buyer has agreed to the advertised price.
An alternative must be available for the transaction actually being offered. For example, an online seller cannot make an online card fee “optional” merely by saying that you could travel to a physical location and pay cash. The cash option has to be realistically available for that offered transaction.

When the credit-card option is genuinely optional
If the merchant offers a workable way to complete the same transaction without the card fee, the surcharge can be excluded from the base total only when the business clearly and conspicuously discloses its nature, purpose, and amount before you consent to pay it. A statement that appears after you click the final purchase button is not advance disclosure.
Look for the fee before entering card details or confirming the order. The disclosure should identify that the charge is for credit-card or payment processing, state the amount or rate, and make clear that another payment method can avoid it when that is the merchant’s basis for treating the fee as optional.
State prohibitions remain in force
The FTC’s final rule, published in the Federal Register on January 10, 2025, expressly preserves state laws that prohibit credit-card surcharges. Meeting a federal disclosure requirement therefore does not authorize a fee that the transaction’s state or territory forbids.

What to do at the checkout screen or counter
- Ask whether the same transaction can be paid without the fee. Confirm that the alternative works for the purchase you are making, not merely at a different store, through a different channel, or for a different product. Ask whether cash, debit, electronic transfer, check, or another method is accepted without the surcharge.
- Find the disclosure before you consent. Check the price page, order summary, posted sign, menu, contract, or terminal screen. The fee’s purpose and amount should be understandable before you approve payment. Compare the amount shown before approval with the amount on the receipt.
- Ask for an explanation if the numbers differ. A percentage displayed at the entrance may produce a different dollar amount at checkout if the taxable or financed base changed. Ask the merchant to show the calculation and identify the legal or network basis it is relying on.
- Choose the fee-free option or decline. If an acceptable alternative exists, use it. If you do not want to pay the surcharge, tell the merchant you are declining the transaction. The U.S. General Services Administration’s SmartPay guidance also suggests considering another merchant offering the same or a similar item.
- Preserve evidence if you think the fee is improper. Keep the receipt, screenshot the advertised price and checkout disclosure, note the date and location, and record whether the alternative payment method was actually available. Those facts determine which rule may apply.
- Check the law for the transaction’s location. Federal rules leave state approaches in place. Use the current statute and the complaint process for the state or territory where the sale occurred; an online purchase may require examining the seller’s stated location and the transaction terms.
Why the state or territory changes the answer
There is no single nationwide permission slip for credit-card surcharges. The following current statutory examples illustrate the difference; they are not a complete fifty-state survey.
| Jurisdiction | Rule shown by the cited statute | Source |
|---|---|---|
| Florida (2025) | A seller or lessor may not impose a surcharge for choosing a credit card when it accepts credit-card payment, subject to the statute’s stated exception for approved state or federal tariffs. | 2025 Florida Statutes § 501.0117 |
| Kansas | A surcharge may be imposed only when its amount is disclosed clearly and conspicuously in advance at the point of entry or point of sale. | Kansas Statutes § 16a-2-403 |
These examples demonstrate why a fee cannot be judged from the receipt alone. In Florida, a properly printed notice may not cure a surcharge prohibited by the statute. In Kansas, advance point-of-sale disclosure is a stated condition for imposing the charge. The controlling law may also depend on the transaction date, the merchant’s business type, and statutory exceptions.
Card-network rules add limits but do not override state law
Even where a surcharge is not prohibited by local law, the merchant must follow the relevant card-network requirements. Mastercard’s U.S. merchant guidance requires clear notice at the point of interaction and says the surcharge amount in dollars must appear on the transaction receipt. The page describes a maximum surcharge cap of 4%, with additional limits tied to the merchant’s cost of acceptance and card-product rules. See Mastercard’s U.S. merchant surcharge rules.

The GSA SmartPay Bulletin No. 017 likewise describes a 4% outer ceiling and a limit connected to the merchant’s negotiated acceptance rate. These figures are network-rule ceilings, not proof that a particular fee is legal in your jurisdiction.
| Rule source | Requirements or ceiling described | What it does not establish |
|---|---|---|
| Mastercard U.S. merchant guidance | Clear point-of-interaction disclosure; dollar amount on the receipt; maximum surcharge described as 4%, subject to cost-of-acceptance and card-product limits. | It does not authorize a surcharge prohibited by state or federal law. |
| GSA SmartPay Bulletin No. 017 | 4% maximum described, with a further limit tied to the merchant’s negotiated acceptance rate. | It is guidance on network and government-card acceptance, not a nationwide exemption from state bans. |
If a receipt shows a fee above the applicable cap, omits the dollar amount, or differs from the notice you saw, document that discrepancy. The network rule may give you a separate basis to raise the issue with the merchant or card issuer, but the governing law still depends on the transaction.
Recommended Free Tools
First identify what kind of fee you were charged
Businesses sometimes use “service fee,” “convenience fee,” “technology fee,” or “processing fee” for charges that are not all legally identical. The key question is whether the amount is imposed because you chose a credit card, or whether it pays for a separate service available under defined conditions.

- Credit-card surcharge: an added amount tied to choosing a credit card, usually expressed as a percentage or separate line item.
- Mandatory service or processing fee: a charge applied regardless of payment method. If mandatory, the FTC’s rule requires it to be included in the total price rather than revealed only at the end.
- Optional convenience charge: a fee for selecting a particular channel or service, which still requires clear disclosure and may be restricted by other laws.
Ask whether the amount disappears when you switch payment methods. If it does not, the merchant may be describing a different fee; that label does not by itself decide legality. Examine the contract, posted terms, and the exact wording on the receipt.
When refusing is the practical solution
The fee appears only at the last step
Pause before clicking “Place order” or handing over your card. Capture the earlier price and the final screen. Tell the merchant you did not receive advance notice and ask for a revised total or a fee-free method. If the merchant will not change the terms, cancel rather than authorizing payment.
The merchant says cards are accepted only with a surcharge
Ask whether another payment method works for the same transaction. If no viable alternative exists, the fee is treated as mandatory under the FTC framework and should be in the total price. Whether the merchant may impose it at all still depends on the jurisdiction’s law.

Do not assume a posted percentage permits any final amount. Request an itemized calculation. Mastercard’s guidance calls for the surcharge amount in dollars on the receipt, so a missing or contradictory amount is worth preserving as evidence.
You already paid
Start with the merchant’s billing department and provide the receipt, disclosure, and a concise explanation of the discrepancy. If the business refuses, check the applicable state or territorial complaint route and ask your card issuer whether it accepts a billing dispute for an inaccurately disclosed or unauthorized amount. Card-issuer procedures and deadlines vary; follow the instructions on your statement rather than assuming a dispute will automatically succeed.
A decision checklist for evaluating a specific charge
Work through these questions in order:
- Where did the sale occur, and which state or territory’s law governs it?
- Was the payment method a credit card, and is the fee actually tied to that choice?
- Could you complete the same transaction with a workable fee-free method?
- Was the fee’s nature, purpose, and amount shown clearly before you consented?
- Does the receipt show the surcharge in dollars, and does it match the earlier disclosure?
- Is the amount within the applicable network ceiling and the merchant’s cost-of-acceptance limit?
- Does the jurisdiction prohibit the charge even when notice is provided?
A “yes” or “no” to one question does not settle the others. For example, a 2% fee can still be prohibited by state law, while a fee under a 4% network ceiling can still be deceptive if it appeared only after authorization.
Quick Recap
Common mistakes to avoid
- Assuming every surcharge is illegal nationwide. State approaches differ, and the FTC rule preserves state prohibitions rather than creating one national ban.
- Assuming every surcharge is legal if a sign exists. Disclosure cannot cure a state prohibition or a fee that was not actually disclosed before consent.
- Treating “cash accepted” as a sufficient alternative. The option must work for the transaction offered; an unrelated in-person location may not qualify for an online purchase.
- Confusing a network cap with permission. The 4% figures described by Mastercard and GSA SmartPay are limits within their guidance, not a license to charge in every jurisdiction.
- Trying to force the sale without the fee. You can decline or select an available alternative, but the cited rules do not establish a general power to compel the merchant to sell on different terms.
